In this paper, the microstructure and properties of 700 MPa grade beam steel with such two composition designs as low C+Mn+Ti and low C+Mn+Ti+Nb are compared and analyzed. The results showed that the plasticity of single Ti microalloyed product and that of Nb-Ti multi-microalloyed product were the same with the same strength, but the low temperature impact toughness of single Ti microalloyed product was poorer so that its brittle transition was at -20 ℃, while the brittle transition of Nb-Ti multi-microalloyed product was at -50 ℃. It could be improved through increasing the rolling reduction of the first pass of rough rolling and thickness of intermediate billet so as to reach the control level of Nb-Ti multi-microalloyed products.
